— [ Password Disclosure Vulnerability ] —

Hamachi is a Client for Trusted VPN Tunneling.
It presents a Password Disclosure Vulnerability, because User and Passwords
are not correctly protected for Memory Sniffing Attacks, so a local attacker,
with a basical Process Memory Dumper, could obtain the Connection Password.

— [ PoC ] —

If a user has saved him/her own Password, a malicious user can launch a
Process Memory Dumper and look through the dumped memory and with a simple
string searching he can retrieve user /password

Useful keywords:

USERNAME
XCHAT_WARNING_IGNORE=

• No patch available from the vendor.
